7/25 – Rob’s Mid-Week “Changing Pattern” Forecast

Upper trough over the eastern US remains anchored along the mid-west/NE with an upper-level high pressure centered over Arizona. At the surface, the frontal boundary that brought drier air to the area is well south and east of even our coastal waters.

The upper-level trough will gradually fill and eventually lift out by Friday. While it is possible for a few storms to develop during the heat of the day near colliding lake/sea/outflow boundaries today and Thursday, areal coverage is expected to be extremely limited, and not high enough to justify carrying in the forecast until Friday afternoon. Even then, we are talking rain chances mainly below 30 percent.

We will continue to trend high temperature forecasts toward the hotter solutions.

Dew points should not be high enough to allow heat index values to reach advisory levels in most areas, but it could be close on Friday going into the weekend.
